| 摘 要： | 受磁暴影响，电力系统变压器集群无功损耗剧增构成系统电压稳定问题的重大威胁。在分析电力系统磁暴灾害扰动故障机理的基础上，将磁暴造成的变压器集群无功损耗进行合理等效，根据电压与电力系统参数的关系式与燕尾突变流形的正则形式相同的特性，在突变理论基础上提出了电压稳定性指标和判断方法，NewEngland 10机39节点的数值仿真结果表明所提方法的有效性。

| Abstract: | The rapid increase of transformers cluster reactive power loss resulted from geomagnetic disturbance (GMD) threats the system voltage stability fundamentally. Whether the voltage is close to collapse or not will help operator in time to take scheduling measures to avoid a more serious accident. Based on the analysis of the fault mechanism of the power system due to GMD, the transformer cluster reactive loss is made reasonably equivalent and the method and index of voltage stability judgment based on catastrophic theory is proposed according to the same features of relation between voltage and power system parameter and the canonical form of swallowtail catastrophe. The simulation on the 10-machine New-England power system with 39 nodes shows the effectiveness of the method. |
